CC   -!- FUNCTION: Catalyzes the ATP-dependent transfer of a sulfur to tRNA
CC       to produce 4-thiouridine in position 8 of tRNAs, which functions
CC       as a near-UV photosensor. Also catalyzes the transfer of sulfur to
CC       the sulfur carrier protein ThiS, forming ThiS-thiocarboxylate.
CC       This is a step in the synthesis of thiazole, in the thiamine
CC       biosynthesis pathway. The sulfur is donated as persulfide by IscS.
CC       {ECO:0000255|HAMAP-Rule:MF_00021}.
